Loyalists of New Brunswick

Loyalists of New Brunswick

I am using Esther Clark Wright's "The Loyalists of New Brunswick" for research. She has a key to the list of abbreviations in her list of New Brunswick Loyalists, but some of them are missing from the key. For example, in N.Y. D. Co., I know N.Y. is New York. Would it be D. Company of the New York Volunteers? Another entry says N.Y. D. Co. WL, but WL is not in the key. What is WL? Ens. is not in the key, but seems to be a military rank--Ensign? I have an interlibrary loan of a first edition, so perhaps the missing information was corrected in a later edition. Can someone help?
